To make each video more attractive to the viewer's eye, you're going to want to add some movement or "transitions" to each scene.
These can be randomized throughout the video by toggling on the "transitions" button or can be uniquely selected per each scene. Either way, you will not see these transitions in your real time preview.
In order to view your transitions, click on "preview and produce." From there you can take a sneak peak to see how things look and either go back into your editing window to make changes or produce it for your fully rendered version!
